Designers hope hydrogen-powered plane will fly halfway around the world without refueling

2년 전 제출됨

One of the toughest nuts to crack when it comes to developing carbon-free transportation is flying. Commercial electric planes won't be feasible until batteries become more powerful and lightweight. Hydrogen-powered flight is another possible way forward, and a research group has revealed what such a plane could look like. The FlyZero project, which is led by the Aerospace Technology Institute and funded by the UK government, came up with a concept for a liquid hydrogen-powered midsize… (www.engadget.com) 기타...

A little more data - Boeing's concern fuel volume will make the plane inefficient.

halfway around the world is a laudable goal, but real live people/passengers will have to endure the strain of such a flight. How many hours endurance will such an airliner consume in this pie in the hydrogen-sky ideal? Suspended animation would be timely here, but don't hold your breath. Any time line operating here?

The headline is misleading because the article mentions one refueling stop.

The energy density of hydrogen isn’t nearly as good as that of jet fuels, so in order for this aircraft to fly halfway around the world it would need to be essentially a tanker in the sky, or fly with a minimal load of passengers and cargo. From the looks of the fuselage it is designed to carry a huge amount of fuel, which is very inefficient.

Hydrogen is lighter than air, I hope they have a way of keeping an aircraft with that much fuel on the ground before takeoff.

The article mentions that "cryogenic fuel tanks ... would store hydrogen at -250 degrees Celsius". The hydrogen will therefore be in liquid state, which is heavier than air.

It's only lighter than air at ambient pressure, not when compressed and liquified (as is the case in this application). One gallon of liquid hydrogen weighs about 0.6 lbs.

Thanks, I didn't know that.

I am 71 and H2 and Electric aircraft are not going to be practical in my remaining lifetime. But my money would be on H2 long before Electric for long Haul airliners. the Safety and if I cared environment impact is both likely not fully understood with super cooled H2. And as the H2 is burned we get Water vapor which is 1000s of times more of a Green house gas then CO2 and CO.

Just curious why safety would matter to you if environmental impact doesn’t.

Envirormental impact Of burning Fossil Fuel is not life threating as the emissions of CO2 and Co have only minor impact on the Climate. Solar cycles and Orbital Mechanics are 99% of climate. Man made Climate change is a over blown. When you understand the true cause of climate Change then you understand the insanity of Man made climate change. Also the Climate is always changing it is either getting warmer or it is getting cool and it takes centuries to see a real trend. Climate change and likely this never ending Pandemic is more about controling the masses, It all stems with a drive to create A OWG similar like the CCP of China. Get a grip on living and not being taken in by the Woke Crowd.

That is your opinion, but it is not supported by published scientific evidence.

While it's true that water vapor is a greenhouse gas and it does have a major impact on atmospheric temperature, it's effect is very different to gases like carbon dioxide. The amount of water vapor that can be held in the atmosphere is limited by temperature and when the limit is exceeded, the vapor turns to liquid and the water is released as rain. With CO2, there is no limit. The concentration can increase indefinably.

To fly that far, I hope they are including extra high capacity lavatories!

>>>>>cryogenic fuel tanks in the rear fuselage, which would store hydrogen at -250 degrees Celsius (-418 degrees Farenheit). Two smaller "cheek" tanks along the forward fuselage would keep the plane balanced as fuel is used.<<<<<

I would be interested in seeing the W&B charts before this concept is put into play. Given that the storage is liquid in nature. I wonder how much their "cheek" tanks will hold? Lots of questions the author should have asked.

Hydrogen is lighter than air, will they us anchors to keep the aircraft on the ground?

This fuel has been touted for years yet nothing of value so far more specualtors trying to make money off of so far nothing of value. HO HUM where is that flying car anyway?
